SPECIFICATION forming part of Letters Patent No. 326,004, dated September 8, 1885.

Application filed June 1, 1885.. (Nb model.)

To all whom it may concern:

Be it known that I, ELIJAH S. WILBER, a citizen of the United States, residing at Ohicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Heaters, of which the following is a specification, to wit:

This invention relates to heaters; and it con sists in the peculiar construction and arrangement of the same, substantially as will be hereinafter more fully set forth and claimed.

In order to enable others skilled in the art to which my invention appertains to make and use the same I will now proceed to describe its construction and operation, referring to the accompanying drawings, in which- Figure 1 is a front elevation, Fig. 2 a vertical section, and Fig. 3 a cross-section, of a heater in which are shown my improvements. Fig. 4 is a modified cross-section of the shell.

This heater is of the kind used for heating by connection with coils or radiators, through which hot water or steam is circulated to accomplish the desired object.

A represents the shell of my heater, which is made circular or any other desired form in cross-section, and all or as much thereof as is necessary made of rings a a, one upon the other, and eachformed in two portions which are hinged together, so that one may be swung back at any time to gain admission to the interior for cleaning or repairs, as will be hereinafter more fully explained;

This heater is provided with a grate, A, of any kind found preferable and above the grate is a firepot, B, formed of a coil of pipe, b, one end of which is passed through the shell and connected to a stand-pipe, B, and the other end led off in a similar manner to a second stand-pipe, 13 as shown fully in Fig. 2.

The shell above the fire-pot is provided with a reservoir or feeder, B for containing fuel, access to which is had by means of a suitable door, I), in the shell near its top. Around the feeder are arranged a series of horizontal coils of pipe, 0. These coils are closely wound, to prevent the pas'sageof hot air and products of combustion through them as much as possible, and spaces 0 are left around them alternately at their inner and outer sides, so that the flame, heated gases, &c., arising from the fire pass around between one of these coils and the shell, then back and between the next coil and the feeder, and continue thustill the last coil is passed and they are free to escape up the chimney'A This arrangement, it will be seen, causes all the heat and products of combustion to pass back and forth over the entire surface of each pipe-coil, and utilizes all the heat to the utmost extent before it escapes.

Each coil 0 is at one end connected to the stand-pipe B, and at the other to the pipe B the first connection being preferably made at a point below the level of the other, in order that by reason of the tendency of hot water or steam to rise the circulation through the coils and stand-pipes may be always in the required direction. to a circulating-pipe, b and the stand-pipe B with a circulating-pipe, b, which form the supply and return pipes to the series of coils orradiators, to which they are connected in the usual manner.

When the pipes are filled with water and a fire started, the water in the horizontal coils becomes heated and rises into the stand-pipe B, being at once replaced by a supply from the pipe B, and thus a constant circulation of heated water is obtained, which is passed through a series of radiators in various locations, and then returned to the heating-coil. The heater is herein represented as arranged for hot-water heating, and connected with a system of radiators of considerable extent; and I have therefore shown a number of heating-coils in order to increase the heating-surface exposed to the fire, and thus induce a more rapid heating and circulation of the water. It is evident, however, that a greater or less number of these coils will be used, according to the service required, and in some cases additional coils, G, are placed vertically around the shell and feeder, as shown, and connected with the stand-pipes as before, thus gaining the utmost service from a small amount of fuel. when steam is used for heating, I employ the same device shown, except that the pipes are not entirely filled with water, and two or more of the heating-coils are connected together, in order that the water may remain underthe action of the heat a sufficient time to vaporize it.

Should it become necessary at any time to The pipe B is connected clean or repair the coils, access may be had. to any particular one by turning back one of the hinged and sectional rings a a.

This mode of construction, while practical, necessitates the disconnection of the coils when the hinged sections are swung back, and I prefer, therefore, to use the form shown in Fig. 4, in which the stand pipes are both placed on one side of the heater, and the-ad jacent side of the shell formed solid, while the other half of the shell is in two hinged parts.

open at will to give access to the coils, and any particular coil is drawn out readily when disconnected.

Having thusful'ly described my invention", what I claim as new, and" desireto secure'by Letters Patent, is'- 1. In a heater, thecombination, with the shell'and its fire-pot, of a series ofhorizontal pipe-coils having smokeescape openings alternately at their periphery and center; substantially as and for the purpose set forth.

2. In a heater, a shell formed of a series of sections,each made in two parts hinged together, whereby any portion ofthe interior may be opened up atwill, substantial-l y as and for the purpose set forth.

having alternate escape openings through them for the smoke, and connections between 35 them and the stand-pipes, whereby the smoke andheated gases are caused to circulate under and over all parts of each heatingcoil,

substantially as and for the purpose set forth. This enables the hinged parts to be swung I1 In a heater, the shell A, formed with 0 several hinged two-part sections, a a, and having a central reservoir or feeder, B, in coinbination withv the stand-pipes B B connected ito the radiating system, the coil of pipe I), forming therfire-pot', and the horizontal coils O ,..havi=ngopenings-c alternately at their outer 5 and inner edges, all of' these coils" connected to-on'e' of saidstand'pi'pes at a lower level f than their connectionwith the other, substan tially as and for the purpose set forth...

50 In testimony whereof I- affix my signature in presence ct two witnesses. I
